N.M. Code R. § 3.5.4.11
TAXABLE IN ANOTHER STATE; WHEN A TAXPAYER IS “SUBJECT TO” A TAX – FOR TAXABLE YEARS BEGINNING ON OR AFTER JANUARY 1, 2020: For periods beginning on or after January 1, 2020. New Mexico follows the so-called Finnigan approach. This approach determines when a corporation will be deemed to be taxable in New Mexico as well as to the question of when a taxpayer is “taxable in another state” for purposes of Section 7-4-4 NMSA 1978, and sourcing of sales under Sections 7-4-17 and 7-4-18 NMSA 1978. In general, under the Finnigan approach, New Mexico looks to the activities of the unitary group, or if the group has elected to file a consolidated return, to the activities of the consolidated group, to determine if any member of the group is taxable in New Mexico or in another state. If the group, or any member of the group, could be subjected to New Mexico corporate income tax under both constitutional principles and any applicable federal statutory law, then all members of the group are taxable in New Mexico. Similarly, when determining if a member of the group is “taxable in another state,” if the state has jurisdiction to impose such a tax on the unitary business in whatever form it may allow that unitary business to file, whether or not it does impose such a tax, then all members of that unitary group are taxable in that state. This version of this section applies to taxable years beginning on or after January 1, 2020.
